To phase out fossil fuels and reach a carbon–neutral future, solar energy and notably photovoltaic (PV) installations are being rapidly scaled up. Unlike other types of renewable energies such as wind and hydroelectricity, evidence on the effects of PV installations on biodiversity has been building up only fairly recently and suggests that they may directly

Renewable energy in the United Kingdom/Rooftop Solar PV

Rooftop solar panels are often very visible - they should be fairly easy to map. And to a small extent, once mapped they serve as landmarks for within residential areas. Solar panels mapped as areas are already displayed in Open Infrastructure Map or the data can be used for other analyses of the UK''s power network.

Impact of solar PV on aviation and airports

The FAA guidance on this topic states: solar PV employs glass panels that are designed to maximize absorption and minimize reflection to increase electricity production efficiency. To limit reflection, solar PV panels are constructed of dark, light-absorbing materials and covered with an anti-reflective coating.
